I am storing accelerometer data in a csv file. The rate is 1000 samples per second. To see whether everything is perfect or not, I put the XDK on a table, and hit the table 4 times. So, if I plot the data in time domain, I should get 4 hit strike, which I am getting, but there are some anomalies in the accelerometer data especially in the -ve g values. If we look at the plot, we see, unnecessary values in the -ve g. May be the accelerometer output is saturating in the negative direction. To make the situation clear, I am posting 2 images, one with anomaly(the left one); the other with a result that I should have(the right one). (The correct result is measured using the datalogger demo.) Can anyone help me with this?
